P1口扩展实验 P1口既做输入口又做输出口，KEY1做为左转弯开关，KEY2做为右转弯开关。LED5、LED6做为左转弯灯，LED7、LED8做为右转弯灯（如图2-2）。 编程实现汽车转向灯功能，即：KEY1接高电平KEY2接低电平时，右转弯灯灭，左转弯灯以一定频率闪烁（注意：KEY拨向上方为0）；KEY2接高电平KEY1接低电平时，左转弯灯灭，右转弯灯以一定频率闪烁；KEY1、KEY2同时接低电平时，发光二极管全灭；KEY1、KEY2同时接高电平时，发光二极管全亮。(P1 I extended not only to do experiments P1 I also do input output, KEY1 switch as a left turn, KEY2 as switches and turn right. LED5, LED6 as a left turn lights, LED7, LED8 as lights and turn right (Figure 2-2). Programming car turn signal function, namely: KEY1 high key2 access low-level access, the right turn lights out, left turn to a certain frequency of flashing lights (Note: KEY allocated to the top to 0) KEY2 access high Key1 low-level access, the left turn lights out, turn right to a certain frequency of flashing lights KEY1, KEY2 low at the same time, the light-emitting diode body KEY1, KEY2 high at the same time, the light-emitting diode light-wide.)

stc12c5a60s2单片机，I2C接口通讯程序，可实现I2C总线的启动，停止及握手等功能(stc12c5a60s2 microcontroller, I2C interface communication program, can be realized starting I2C bus stop and other functions handshake)

28335的spwm输出，开环测试，三相spwm信号分别为epwm1~6，频率为20KHz(spwm output 28335, the open-loop test, three-phase spwm signals are epwm1 ~ 6, frequency 20KHz)

3． 参考void Reverse(LinkQueue &Q)函数，定义新的函数int Palindrome_Test(char str[])，判断字符串str是否回文序列,若是则返回1,否则返回0。写出程序或用文字描述算法的执行步骤。(3. Reference void Reverse (LinkQueue & Q) function, define a new function int Palindrome_Test (char str []), to determine whether the string str palindromic sequence, if it returns 1, otherwise it returns 0. Written procedures or describe in words the steps of the algorithm.)

程序1：stm32程序串口2接收串口1发送程序 ，改自扩展实验11 ATK-HC05蓝牙串口模块实验程序。 程序2：zigbee串口通讯-发送字符串。 连接方式：cc2530的P02连接stm32的PA2，P03连接stm32的PA3 程序2串口一直发送“hello zigbee”字符串 mini版stm32程序1串口2接收后转发串口1原样输出。(Program 1:stm32 program serial port 2 receive serial 1 send program, change from expansion experiment 11 ATK-HC05 Bluetooth serial module experiment program. Program 2:zigbee serial communication - send string. Connection mode: CC2530 of P02 connection, STM32 of PA2, P03 connection of STM32 of PA3 Program 2 serial port has been sent "Hello ZigBee" string mini version of STM32 program 1 Serial 2 receive after forwarding the serial port 1, the original output.)
